What is ozone at ground level.

Answers

Answer 1
Answer: Here is something I found on google, hope this helped ☻: Ground level or "bad" ozone is not emitted directly into the air, but is created by chemical reactions between oxides of nitrogen (NOx) and volatile organic compounds (VOC) in the presence of sunlight.
Answer 2
Answer: ozone layer in the stratosphere, ground level ozone is a harmful air pollutant that affects all of us. It's formed when emissions from everyday items combine with other pollutants and “cook” in the heat and sunlight.

How does the contractile vacuole in a single-celled organism function to maintain homeostasis?a. It pumps water into the cell.
b.It pumps water out of the cell.
c.It pumps solutes into the cell.
d.It pumps solutes out of the cell.

Answers

Answer: "Option B- It pumps water out of the cell".

Explanation:

Vacuoles in the cell organism are responsible to maintain the amount of water in the cell body, to get stable in the environment vacuoles either  remove or absorb the water through the mechanism of osmosis or osmoregulation.

Homeostasis is the phenomenon of maintaining balance of physical and chemical conditions of organism according to the environmental conditions to survive in it.

In single celled organisms, contractile vacuole pumps out the water from the cell through osmoregulation and excess of water is pumped out by the contractile vacuole.      
It's b. When placed in a freshwater environment, the organism is in a hypotonic solution, so water would flow into the organism. To prevent from bursting the vacuole constantly pumps water out to make up for this.

Answers

It plays an important part in the development of embryos, and it is important for the growth and development of our bodies as well. Mitosisproduces new cells, and replaces cells that are old, lost or damaged. In mitosis a cell divides to form two identical daughter cells.
Mitosis is the simple duplication of a cell and all of its parts. It duplicates its DNA and the two new cells (daughter cells) have the same pieces and genetic code. Two identical copies come from one original. Start with one; get two that are the same.

Distribution of water and nutrients to the flowers affects seed formation

Answers

Distribution of carbohydrates from the leaves to the other parts of the plant is affected.

The main function of the Xylem is to transport water and minerals throughout all parts of the plant. Phloem on the other hand is responsible for transporting organic molecules that are larger in size. The vascular system, consisting on the Xylem and the Phloem runs from the roots of the plats through the branches and upto the leaves. It controls the total transportation of the water and nutrients.
